I am working on an android app that will be used by students to register at schools. I want the different school offices to be able to send push notifications to specific students. I implemented the firebase example and were able to send a push notification to a specific device.
When a student registers I can fetch the registration ID and save it so the office knows which ID belongs to the specific student. That is needed to target the correct student, right?
Do I need to write an external program that lets the offices enter those IDs to send push notifications? How would they get their sender IDs? Or is there another way or already established practice for similar use-cases?
As you probably noticed I am a bit confused about that; any help appreciated.
